MITER-GLAMP.

Specification of Letters Patent.

Patented Oct. 17, 1916.

i Application filed January 28, 1916. 7 Serial No. 74,902.

' To all whom it may concern: a

. Be it known that I, GUSTAV J. E. STEUBER, a citizen of the United States, residing at 2625 Bellefontaine avenue, Kansas City, in the county of Jackson and State of Missouri,

. have invented new and useful Improvements in Miter-Clamps, of which the following is a specification- This invention relates to a clamp which may be applied to the sections of a miter for holding said sections in mitered relation irrespective of the miter or length of the sections.

The primary object of the invention is to opposite directions to separate the joint suificiently far to enable glue to be placed upon the side edges thereof.

Another object of the invention is to provide clamping arms for the clamp so constructed that they may be connected with the attaching bars of the clamp after the same have been applied to the respective sections of the miter. v

A still further object of the invention is to provide the clamp with L-shaped supporting members having grooved ends which may be arranged to receive the attaching bars of the clamp after said bars have been secured to the respective sections of the miter to prevent the sagging of said bars when the clamping'arms of the clamp are in clamping engagement with the sections of the miter.

A still further object of the invention is to provide the clamp with attaching bars having rabbeted side edges which are recessed at intervals throughout the length of said barsto enable the spacing members,

- clamping arms and the supporting bars to be engaged with the attaching bars after the same have been applied and clamped to the respective'sections of the miter.

With these and other objects in view the invention resides in the novel combination and arrangement of parts, which will be herein after described, and particularly pointed out in the claims.

The preferred form of the invention has been illustrated in the accompanying drawing, although no restriction is necessarily made to. theprecise details of construction therein shown, as changes, alterations and modifications within the scope of the claims may be resorted to when so desired.

In the drawing: Figure 1 is a detail perspective view of theimproved clamp show ing the same applied to a miter, Fig. 2 is a vertical transverse sectional view on the line 2+2 of Fig. 1 looking in the direction of the arrow, Fig. 3 is a view similar to Fig. 2 to better illustrate the construction of the clamping arms. Fig. 4 is a view similar to Fig. 3 to more clearly illustrate the construction of the supporting members used in connection with the clamp, Fig. 5 is a side elevation of one of the attaching bars of the clamp showing the same removed from themiter and having the spacing members, clamping arms and supporting mem sponding parts throughout the several views in the drawing in which "the numeral 1 designates the sections of the miter which are joined, as at 2 to complete the miter joint.

Arranged upon opposite sides of the sections 1 are attaching members 3, each comprising a bar 4 having rabbeted side edges 5 which, are provided at spaced intervals throughout the length of the bar with notches 6 while slidably mounted upon the bars 4 are sleeves 7.

The sleeves 7 are shaped to-correspond to the shape of the bars 4 which they encircle and have a portion thereof snugly fitting within the rabbeted portion of said bars, while depending from the under side of the sleeves and spaced therefrom for a greater portion of their length are arms 8 the free ends of which are provided with set screws 9. The sleeves 7 are recessed on their under side, as indicated at 10 so that, a portion of the bars 4 disposed in said sleeve will contact with the sections of the miter when the bars are positioned thereon with the ends of the sections disposed between the arms and the sleeves, thus it will be seen that when the set screws 9 are tightened one end thereof will bear against the under 'side of said sections and force the same into contact with the bars thus holding the bars positioned upon the sections and the sleeves securely clamped between the bars.

Spacing members 11 are provided for connection with the bars 4: and each comprise a companion section 12 and 13, each of said sections having an "end' grooved to recelve the bars 4 with the side Walls of the grooves 5 recess-ed to snugly fit Within the grooves the rabbeted sides of sald bars, said grooves body ojt said members. l/Vhen the bars 4are v in clamping position upon the sections the offset ends of said members Will overlap and enable a stud 15 inthe end of the offset portion of-the member 13 to be positioned Within a groove in the end of a the offset portion of the section 12Whereby, the said sections are removably and hingefdly connected. Through the above described construction of the spacing members it Will be seen that When the sections thereof are applied to the clamping bars '4 the said bars may be-spaced a suitable distance from the mitered edge of the sections and then clamped to saidsecti'ons in such a manner as to cause'thestud lo-on the sections 13 to be positioned Within the grooves 16 inthe section 12 thus-enabling the sections of the miter to be swung apart a su'lficient distance to permit glue to be inserted upon the miterededgesof'said sections and upon swingingthe sections in the reverse directionthe mitered edges thereof will becaused to contact andheldin such relation through the connection of the spacing-members With *the attaching bars of the clamp. p In order thatthe sections of the miter may be held in contactingrelation until the glue sets clamping arms 17 are provided each of which comprises companion sections 18 and 19 and each'section of the clamping'arms has an end provid'ed'with' a groove similar to the groove in the end of the spacing members "and designated by the numeral 20. Each section 18 of the clamping arms has its: end distant from that containing the groove 20 provided with a curved finger 21, t-he 'free end of \vhichis provided vvitha set screiv' 22so that when theseo'tions 18 and 19 tlieclaiiiping arms 17 are" in clamping position upon' the bars' lthe set screws may be" tightened 'to' -have" one end thereof bearin notchesf23* in the ends of" the sections 19 of the clamping 1 a rms' thus securing 1 the arms in clam-ping posit-ion upon the "sections of the -=miter.

*lVh'en it is desired to use the clamp for holding miter sections of considerabledength in nritered relation it has fbeen found desirable topr ov'ide supporting members for the bars 4 which in" this instance havebeen shown to comprise l -'shapedmembers designated by the numeral 2 1, said *membershaving their r free ends f'pTOVl'iIlfid vitli'grooves25 "similar to the grooves-in the endsof the clamping arms 17 and the spacing members, said members when engaged with the bars l serving to pre'ventthe bulging orspreading of the bars when the set screws 22 carried by the i fingers on the sections 18 of the clamping arms are tightened to cause the mitered ends of the mitered sections to contact.

\Vhenxitis desired to apply the clamp to a miter the sleeves 7 011 the bars l are adjusted a suiiicient distance apart to enable theends otthe sections to be positioned be.

tudinally along the bars 41 until the stud 15 in the-sections 13 of thespacing men bers are-received in the grooves 16 in'the sections 12 of said member. irfterthe above described operation has been completed it will be noted that *the mitered sections may 1 be swung to a position 'to enable glue" to be placed upon their mitered faces and that the barsd'arespaced an equal distancefrom the mitered faces throughout their entire length to 'iacilitate the proper"adjustment of the clamping arms and supporting members as heretoforedescribed. After the glue has been spread npon the miteredkfaces of said sections the sections may again be swungto position which will causethe mitered' fa-ces of said sectionsto contact and-sections 18 i and 19 of the clamping arms 17 connected Withthe barse by means of the recesses 6, said sections being sli'd longitudinally of the bars between thenotches or recesses'until a point is reached Where it is desired to apply pressureto the miter joints by means of the clamping arms. The set screws 22 are novv tightened so that the ends 01"? the screws bear in the grooves 20 in the sections '19 thus forcing the clamping arm sections in clamping engagement With the miter sections. It will of course be understood" that any number of clamping arms may be employed for this purpose as found desirable and that if the miter sectionsare of considerable length a suificient number of supporting members may'be connected with the bars by engaging the grooved ends er saidmembers with the barsby means of the recesses '6.

From the above statement itWill be seen that the spacing members ll spacethe bars porting members prevent the spreading or sagging of the bars 4 when the clamping arms are in clamping engagement with the miter sections, thus insuring a perfect joint at the meeting faces of the miter sections.

It will be further noted that by providing the bars 4 with the alined recesses 6 in the side edges thereof and providing the sections of the clamping arms and spacing members with grooves snugly receiving the bars 4 the said spacing members and clamping arms and also the supporting members may be applied or detached from the bars 4 after the same have been positioned upon the miter sections.

- From the foregoing statements taken in connection with the accompanying drawing it is at once apparent that a miter clamp has been provided, which is inexpensive of manufacture, simple in construction and highly efficient in use.
